    摘要： A flexible, steerable intravascular catheter includes an elongate flexible shaft having a heterogeneous or multi-zone stiffness profile or structure. A first or distal portion of the catheter shaft may have a substantially constant or distinct stiffness or flexibility, a second, intermediate or transition section is proximal relative to, and less flexible than, the first section, and a third section is proximal relative to, and also less more flexible than, the first section. The third section also includes a substantially constant or distinct stiffness or flexibility. The flexibility or stiffness of the second section varies along its length, e.g., in a substantially linear, step-like or ramp-like manner to provide a smooth or gradual transition between the stiffness of the first or distal section and the flexibility or stiffness of the third or proximal section.

    摘要翻译： 柔性，可操纵的血管内导管包括具有异质或多区域刚度分布或结构的细长柔性轴。 导管轴的第一或远端部分可以具有基本上恒定或不同的刚度或柔性，第二中间或过渡部分相对于第一部分近端并且比第一部分更柔性，并且第三部分相对于第二部分近端， 并且也比第一部分更不灵活。 第三部分还包括基本上恒定或不同的刚度或柔性。 第二部分的柔韧性或刚度沿其长度变化，例如以基本线性的阶梯状或斜坡状方式变化，以提供在第一或远端部分的刚度与柔性或刚度之间的平滑或逐渐过渡 第三或近端部分。
